- Аннотация: Morphological descriptions of two Halomonhystera species (Nematoda, Monhysterida) are presented. Halomonhystera hermesi sp. n. makes up a dense monospecific and homogeneous population on bacterial mats in central zone of the Håkon Mosby mud volcano in the Barents Sea at a depth of 1280 m. The species is revealed as an endemic lineages distinctly separated from other shallow–water cryptotaxa of the Halomonhystera disjucta species complex on the base of mitochondrial gene COI (genetic divergence 19.6–23.8%) and nuclear genetic markers and also on the base of morphometrics by Van Campenhout et al. (in press). Halomonhystera socialis (Bütschli, 1874) is redescribed on the base of the White Sea specimens. This species dwell in mass on the detached kelp accumulation in upper sublittoral. H. socialis is differentiated from other species of Halomonhystera disjuncta complex morphometrically by larger body size and by genetic divergence in nuclear markers. The genus Halomonhystera Andrássy, 2006 is redefined and its morphospecies list is reviewed. Species H. bathislandica (Riemann, 1995) comb. n., H. fisheri (Zekely et al., 2006) comb. n., H. islandica (de Coninck, 1943) comb. n. and H. vandoverae (Zekely et al., 2006) comb. n. are transferred from Thalassomonhystera; H. paradisjuncta (de Coninck, 1943) comb. n. and H. taurica (Tsalolikhin, 2007) comb. n. transferred to Halomonhystera from Geomonhystera. Halomonhystera ambiguoides (Bütschli, 1874) and H. uniformis (Cobb, 1914) are considered as species inquirendae because of incompleteness of their diagnoses.
